How long does delivery take?  

Delivery takes approximately 4 - 7 working days once the order has been placed, depending on the delivery location.

It is advisable to refrain from scheduling any installation until all products have been received on-site.

How much should I allow for the ZINCALUME® steel sheets to run into the gutter?

We recommend a 50mm overhang into a standard gutter.


What is the ACTUAL sheet width of the corrugated iron? 

The actual sheet width of corrugated sheets is 850mm.  

Sheet Tolerance: Length: + 10mm, – 15mm; Width: + 4mm, – 4mm Make allowance for thermal expansion or contraction for long-length roofs at sheeting ends

Which fasteners do I use for installing the roofing sheets?

Here at Metal Roofing Online, we only use and recommend 12 x 50 Category 5 screws when installing your roof sheeting, as they last considerably longer in the elements. However, in a standard roofing application, when fixing to either timber or metal purlins, we have in our range a Multifix screw which is the perfect choice for this roofing iron. In addition, these can be colour matched to your sheets. 


The famous Lysaght corrugated profile is used in CUSTOM ORB®. It works well with both traditional and modern designs. It's a long, wide, strong, light, cheap, and easy-to-align profile that is long and wide. When you add these features together, you get a great value steel roof or wall cladding.

We use only the best 100% Australian steel for 100% peace of mind, made from BlueScope’s industry-leading brands such as COLORBOND® steel and ZINCALUME® steel. And, of course, all our products are extensively performance tested, backed with the strength of the BlueScope warranty and can be relied on with total and absolute confidence.

When choosing the best roofing or wall cladding for your home, you need to consider the thickness and quality of the substrate supporting your roof. As with any new building material, it is essential to ensure that you take into account that which you are putting on top of it. In this case, we are talking about a roof made of corrugated iron. This is something to consider as a go-to product when it comes to its rustic appeal.

Metal roofs have long been popular in modern homes, and as one of the most versatile and cost-effective options available today, there is no reason why you shouldn't choose them for your next project. Depending on your desired aesthetics, you can select various colours and styles, including slate, tiles, wood, and other materials.

You need to consider how long this particular product will be around and if it will affect your home's value. There is no doubt that metal roofs have a big reputation regarding durability and protection against weather elements. Aesthetically, they are also great at providing value for money and having superior heat retention qualities compared to most other products. This is a crucial feature where we suffer from very high temperatures almost daily.

While there is a large variety of different products and styles on offer, you do have to consider how this will affect the strength and lifespan of your home. For example, those looking for something that will stand the test of time should consider the strength and thickness of their roofing profile. For those who want something with a more contemporary look, there are many options to choose from. People who want something that will stand out from most other homes in the area will also be sure to find a design that fits their needs.

Wall cladding applications are always popular because they can be visually appealing from a distance and are cost-effective in the long run due to their longevity.

Depending on the design of your wall and thickness, you will be able to achieve a beautiful finish that not only suits your home but also complements it. The choice is all yours when it comes time to choose the best roofing for your home in winter.

Steel roofing profiles, including custom orb, are an economical, long-lasting, and durable option with a broad range of architectural possibilities.

They are similar to corrugated iron roofs because they provide more cost-effective solutions than standard tiles. Both systems may be used in applications where aesthetics are pivotal for various user-level dwellings.

Custom Orb: A mid-depth corrugated profile with improved resistance to damage and greater spanning capacity. FEATURES Finish: COLORBOND®, ZINCALUME® Base Material Thickness: 0.40mm, 0.48mm Ideal for areas with high rainfall Suit low pitched roofs Width: 762mm Minimum roof slope: 3° Can be used as roof and wall cladding for both residential and commercial projects.

What Is The Best Material For Roofing and Walling In Australia?

Zincalume is one of the best materials for roofing and walling in Australia. Tiles may have a shiny look. But these materials are not as strong as metal sheets.

This roof product has been the toughest roofing option for Australians. With the advancement of technology, these sheets are now better and stronger. Moreover, steel roofing is available in multiple colours. Hence, metal roofing is the safest option for Australian homes and workplaces.
